Look, roller derby made it clear long ago: Roller-skating isn’t just for kids. Indeed, anyone who’s seen ATL knows that for many, the rink remains the axis for many a social gathering. Tonight, the Southgate Roller Rink in White Center plays host to a next-level lineup of local metal, including heavies such as Princess, Curse of the North, and Perfect Bombs. Rocking riffs and roller-skating: Whoever dreamed this up is on par with the gal who figured out chocolate and pretzels.
